A friends computer recently had some problems. It would turn on and nothing on screen, then the PSU blew up in a puff of smoke. We changed the psu and found that the Motherboard was dead. We have replaced the MB, new ram and new cpu. Now on boot up the system sits looking for the Hard drive, which it eventually does not find. On going into the bios, which takes around 3mins, and attempting to find the hard drive it still finds nothing. I have tried the HD in two other computers as slave and master. I have also tried putting the HD in a USB case, it still sees nothing. I am pretty sure it is dead, however the drive contains my friends daughters school work for her exams next month - she is distraught and so are the parents. Does anyone know of anything we could try bar sending it to a recovery expert (v.expensive). The drive is an IBM deskstar 20.5 GB (model - DTLA-305020). Thanks in advance for any assitance..
